Should you toe in brake pads?
Brake pads need to be set up with a small amount of ‘toe in’, where the leading edge of the brake pad contacts the rim fractionally before the trailing edge This allows the rotation of the wheel to drag the heel of the pad into the rim for improved modulation Toe in also help reduce brake squeal
Why do my brakes squeak when I slow down?
The squeaking noises when braking at low speed is caused by high-frequency vibration of the pads against the rotating disc When the caliper clamps against the rotating disc, it generates friction which leads to vibration So, the squeaking noise will increase if the brake pads are mounted more tightly in the caliper
Should your feet be flat on the ground on a bike?

Why do brake calipers move?
As the caliper has the ability to slide laterally across the rotor, it only needs to employ a single-piston Progressive foot-brake pressure will then cause the brake caliper to slide across on its pins (Bolts) and at the same time pushing forcefully the outside pad against the outer rotor surface
How do I get my brake caliper piston back in?
In order for the brake caliper to fit over the thicker new brake pads, the caliper piston will need to be compressed backwards by using a “C” clamp Attach the “C” clamp to the caliper piston using the back of an old brake pad to evenly distribute the force across the piston
